2 Claims.

The present invention. relates to lighting fixtures, and is more particularly directed toward lighting fixtures designed for mounting close to the ceiling over dining-room tables andthe like.

lhe present invention contemplatesa lighting fixture for this purpose adapted to use a single pendent lamp with a mirrored lower hemisphere, a single enclosing bowl with low transmission and high transmission zones associated with the reflector for directing a substantial amount oith light toward nadir.

The accompanying drawing shows, for purposes of illustrating the present invention, one embodiment in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same.

In this drawing:

Figure 1 is a side elevational View with parts in section; and

Figure 2 is a sectional view atan enlarged scale.

A ceiling supported lamp socket is indicated at l0 and a concentric sheet metal band at l i The socket supports a pendent lamp 52 having its lower hemisphere mirrored or coated,-as indicated by the stippling it. The band it carries three shade supporting screws enter a bead l5 about the upper edge of a. translucent bowl ll. This bowl may conveniently be made of glass and has an upper curved portion l8 of high difiusion and lower transmission and, intermediate substantially horizontalportion it which is preferably lightly etched and therefore of high transmission, and a bottom hemispherical portion 2B of low transmission.

The curvature of the portion it is preferably such that it merges with the shape of the metal i source and much of the reflected light from. the

lamp coating and reflects this light down through the high transmission zone IQ for illuminating.

objects directly below. As this is a harsh light it adapted to with very slight diffusion it produces bright re- 1 flected images in dishes, silverware, glasses and the like on the table directly below the lighting unit.

The low transmission or high diffusion zones :1 may be provided. by enameling glass, or in any other suitable Way, and they receive a small amount of light which'firstescapes up through the opening in. the reflector 2i and is thenscattered about inside the unit.

It is apparent that, within the scope ci the invention, modifications and different arrange merits may be made other than is herein dis? closed, and the present disclosure is illustrative merely, the invention comprehending all variations thereof.

What is claimed is:

1. A lighting fixture comprising a pendent lamp, a bowl having a high transmission, substantially horizontal zone at the height of the light center of the lamp, 2, low transmission zone extending downwardly from the inner edge of the horizontal zone and disposed about the bottom of the lamp, and a low transmission zone extending upwardly and outwardly from the periphery of the high transmission zone, and a reflector disposed above the high transmission zone to screen the upwardly andoutwardly extending zone and reflect upwardly directed light down through the high transmission zone.

. 2. A ceiling lighting fixture, comprising a sup-- porting band secured to the ceiling with its inner edge below the ceiling line, a centrally disposed pendent lamp having a mirror coating on the lower hemisphere, a light diffusing bowl having :7.- an upper portion which is downwardly convex and of low transmission, a flat high transmission zone at the bottom of the low transmission zone and atsubstantiallythe height of the light source of the lamp, and a hemispherical bottom portion of low transmission, an annular downwardly and outwardly flaring reflector for directing light out through the high transmission zone, and bowl securing means carried by the band.
